A potyvirus (isolate PFV-FJ) infecting passion fruit in China was identified by small-RNA sequencing. The complete genome sequence of PFV-FJ was determined to be 9974 nucleotides, excluding the poly(A) tail. PFV-FJ shares 70-72% nucleotide and 69-74% amino acid sequence identity at the polyprotein level with seven reported potyviruses, but 89% nucleotide and 91% amino acid sequence identity with an unreported potyvirus, tentatively named "passionfruit Vietnam potyvirus" (PVNV-DakNong). This suggests that PFV-FJ and PVNV-DakNong should belong to the same potyvirus species and that PFV-FJ is a new member of the genus Potyvirus. This new potyvirus was tentatively named "passion fruit severe mottle-associated virus".
通过小RNA测序鉴定出一种在中国感染西番莲的马铃薯Y病毒（分离株PFV-FJ）。PFV-FJ的完整基因组序列经测定为9974个核苷酸，不包括多聚（A）尾。PFV-FJ在多聚蛋白水平上与七种已报道的马铃薯Y病毒具有70-72%的核苷酸和69-74%的氨基酸序列同一性，但与一种未报道的马铃薯Y病毒（暂命名为“越南西番莲马铃薯Y病毒”，PVNV-DakNong）具有89%的核苷酸和91%的氨基酸序列同一性。这表明PFV-FJ和PVNV-DakNong应属于同一马铃薯Y病毒种，且PFV-FJ是马铃薯Y病毒属的一个新成员。这种新的马铃薯Y病毒被暂命名为“西番莲严重斑驳相关病毒”。
